"Beit known that we, NreoLAs Gomma and HERMA-N BADER, of Cape Girardeau, in the county of Cape Girardeau, and State of Missouri, have invented a new and improved Filter for Cistern-Water; and we do hereby declare thatjthe following is n. full, clear, and exact description thereof, which will enable others skilled in the art vto-make and use the same, reference beinghad to the accompanying drawings, forming part of this speci entio-n. v

.Figure l'represents a vertical central section of our invention.

Figure 2 is aplauortop view of the same', the cover of the tank being removed.v

`Similar letterst ofrefereuce indicate corresponding parts.

This invention relates to a new device for filtering rain-water on its passage from the roof of a building to the `cistern. Such water is generally {illecl'with leaves, pieces ofishingles, and other impurities. The obj-eet of our invention is to clear it of such impurities before it enters the cistern.

The invention consists in the use of a tank or barrel, which is divided, by a vertical partition, into two compartments. The water passes down in one compartment and up in the other, and is, during such passage,

cleansedor ilteredbyseveral sieves and layers'of gravel and powdered charcoal. `A valve is arranged in the side of the barrel for the discharge of water, should thesame -low too qui-ek from the roof, said valve being adjustable, so that Lit can only be opened when the water presses against it with a certain degree of force.

-A represents a tub, barrel, orother suitable wooden or other vessel. `lt-is divided by aver-tical partition,

l l l l l n -a, into two compartments, b ande, :is-1s shown in the drawings. B 1s the cover of the barrel, and 1s held down by means'o'f. bolts d d, or otherwise. C is the pipe from the roof, entering the compartments b through the cover B, asA shown in-thc drawing. The'water from the r'oofilows through the pipe C into thenpper part ot the compartment b, through o. concave sieve, D, arranged across the latter, upon which sieve the coarse impuri- .ties arc deposited. The water then lows'through another sieve, E, arranged somewhat below D i-n' the compartment b, and then enters the lower part of' the compartment 6, which is .lled with a. layer.'v ot gravel. rThe partition-@docs not quite reach to the bottom of the vessel A, and thc water, after it' arrives at the said bottom, l'lows through the opening between the lower end of the partition-and the bottom, e, of the vessel' into the compartments, in the lowcr part ot which powdered charcoal is contained, or other suitable material for absorbing noxious gases.' The water, rising in the compartment c, iows through a sieve, F, into the upper .part oi" the compartment e, and thence off into the cistern through a pipe, Gr. The sicves E and F are for confining the sand and coa-l, to prevent the same from being carried oft' with the water. rlhe siovcs E and F are hinged to the partition a, and rest upon suitable supports projecting from the inside of the vessel A. lH is a valve,

' arranged in the wall of thevessel'A, between the sievcs D and E, to carryoff the water if the same shouldilow too quick, or if it cannot flow any more at all, through the other channels, 'when the eistern is filled, for example. The valve is fitted overa notehj, as shown, and is secured ton. spring, g, the pressure of which can be regulated by a screw, t, as shown in g. 1. I is a faucet for discharging the water wholly from the vessel A'. A sieve, i, arranged over its entrance prevents the sand and coal from also escaping through thei'aueet. J J are Stoppers in the bottom of the vesselfor discharging the sand` and coal whenever desired.v

We cla-im as new, and desire to secure by Letters Patent-- 1. A iilter, consisting of the parts A, B, C, D, E, F, G, and a, substantially as described.

2. In combination with the; above, we claim the valve H, faucetI, and Stoppers J, substantially as herein described.- A i NICOLAS GONNER, HERMAN BADER. Witnesses:
